nodejs upgrade failed

During the development process using Node.js, due to various reasons, we may need to upgrade the Node.js version. However, when you try to upgrade your Node.js version, you may encounter upgrade failures. At this time, we need some debugging skills and solutions to help us solve this problem.

This article will introduce the solution to Node.js upgrade failure on Windows systems, and how to use Node Version Manager (NVM) to avoid this problem.

Node.js upgrade failed on Windows

When upgrading the Node.js version on Windows systems, you may encounter the following error message:

Error: EPERM: operation not permitted, rename 'C:Program Files
odejs
ode.exe' -> 'C:Program Files
odejs
ode.exe.old'

This error This is because when upgrading, Node.js will try to rename the executable file of the current Node.js version (node.exe) to the executable file of the old version, and then rename the executable file of the new version Copy to the same location. However, on Windows systems, file renaming requires administrator rights. Therefore, if you do not have administrator rights, you cannot upgrade Node.js.

The solution to this problem is simple, just run your Command Prompt or PowerShell as administrator.

Using Node Version Manager (NVM)

In addition to failed upgrades on Windows systems, we often encounter situations where we need to switch between different Node.js versions. At this time, it is a good idea to use Node Version Manager (NVM).

NVM is a very useful tool that allows you to install and manage multiple Node.js versions and switch between them easily.

First, you need to download the Windows version of NVM from [NVM’s official website](https://github.com/coreybutler/nvm-windows/releases) and install it on your computer.

After the installation is complete, you can open a command prompt or PowerShell and enter the following command: nvm install x.x.x, where x.x.x represents the Node.js you want to install version number. For example, nvm install 14.16.0 means installing Node.js version 14.16.0.

After the installation is complete, you can use the nvm use x.x.x command to switch to the specified Node.js version. For example, nvm use 12.18.3 means that the Node.js version used in the current terminal is 12.18.3.

To summarize, the problem of Node.js upgrade failure is caused by file renaming that requires administrator rights. It can be solved by running the command as an administrator on the Windows system. At the same time, NVM can be used to easily manage multiple Node.js versions and easily switch between them to avoid upgrade failures.
